Hobbywing XRotor 40A Brushless ESC 2-6S

Optimized for Multi-Rotor Performance

Unlike standard airplane ESCs, the XRotor series features a specialized core program designed specifically for multirotors. This firmware significantly improves throttle response, ensuring your flight controller can make micro-adjustments instantly for better hovering stability and wind resistance. It is pre-configured for “plug-and-play” use with almost all disc-type motors, requiring only a simple throttle calibration to get started.

Interference-Free Signal Transmission

Stability is critical in larger drone builds. The XRotor 40A utilizes a twisted-pair throttle signal cable, which effectively reduces electromagnetic interference (crosstalk) generated by the power lines. This ensures that the signal reaching the ESC remains clean, even in complex builds where power and signal wires are bundled together. It supports high-speed signal frequencies up to 621Hz, making it compatible with all modern flight controllers.

Key Features

• Rapid Throttle Response: Custom firmware outpaces generic open-source software for better flight stability.

• True 6S Support: High-voltage capability (up to 22.2V) for heavy-lift power systems.

• Twisted-Pair Signal Wires: Reduces electronic noise and crosstalk for a more reliable link.

• Intelligent & Adaptive: Automatically adjusts to your motor’s timing requirements for maximum efficiency.

• Ultra-Low Resistance: High-quality MOSFETs ensure high current endurance and minimal heat buildup.
